` Application filed may 4,
To all 'whom t may concern.'
Be it known that we, MAURICE GUY and JOSEPH J. RUIZ, citizens of the United States and of Cuba, respectively, and residents of Detroit, Wayne County, Michigan, have inbers thereof, and its object is to provide means for changing the volume of the explosion space in accordancewith the power developed by the'engine in order to keep the i pressure of the explosive `mixture or fuel at the ends of the compression strokes y substantially constant so as to produce the best results for the fuel'consumed.
This invention c-onsists of-power transm1ssion means and a. resilient connector between said means and the crank shaft of an internal combustion engine, which connector will yield in proportion to the work performed by the engine, means to increase andidecrease the explosion space of the engine, and connecting mechanism between the means for varying the explosion space and the resilient connector whereby such space will be increased or decreased as the resilient connector yields according to the work performed. i
It also consists in the details of construetion illustrated in the accompanying drawing and particularly pointed out in the claims. Y
In the drawing, Fig. 1 is a view, partly in vertical section of that portion of an internal combustion engine which embodies the presentinvention. Fig. 2 is a transverse section in theplane of the upright shaft shown in Fig. 1.
Similar reference 'characters refer to like parts throughout'the several views.
In thedrawng, 1 is an engine embodying I a cylinder 2 having a head 3 provided with a cylindrical extension 4 in which apiston 5 is longitudinally slidable to vary the'explosion s ace at the upper end of the cylinder. l' en the piston 5 is' moved outwardly this space is increased, while the space is decreased to its smallest volume when the piston is at its innermost position.
Mounted in the bearings 6 is a shaft 7 having a bevel gear 8 at fone end and carrying a cam 9 for each cylinder of the engine.. A stem 11 extends up from the piston 5 1923. SeriaI No. 636,572.
through thehead 12 and a spring 10 above this head and below the enlargement 13 at the upper end of this stem pushes the piston upward.
Secured to the crank shaft 14 of the en gine is a threaded hub 15 from which an arm 16 .extends A driven shaft 17 has slidable thereon a vhub 18 whose inner end screws onto the hub 15 and also has an arm 19 connected to the arm `16 by means of a spring 20. The torque of the crank shaft is transmitted to the ldriven shaft 17 by means of the arms 16 and 19 and the spring 20, and theangle between the arms will vary with the power transmitted. As the two hubs are connected'by screw threads, the endwise movement of the hub 18 and the circumferential groove 22 therein willV also depend upon the power transmitted.
A bracket 23 carriedA by a case 24: supports the short shaft 25 on which the arm 26 and bevel gear 27 aremounted. The arm 26 extends into the groove'22 and swings 4substantially in vproportion tothe longitudinal movement of the hub 18 and to the power transmitted. The gear 27 meshes .withthe bevel gear" 28 on the upright shaft 29 at whose upper end is the bevel gear 3() which meshes with the gear `8 on the shaft' 7. vThe cam 9 is therefore turned in proportion to the longitudinal movement of the hub 18 and to the work performed by the engine and the explosion space will therefore also change with the work.
The fuel burned in an internal combustion engine shouldvvary approximately with the work performed when the engine is running at constant speed, but this is only approximately as the power delivered by the engine varies because the compression of the .fuel is anything but constant. When fuel charges vary in amount, the terminal pressures alsovary, and as the explosive force of each fuel is apparently greatest when the fuel is at a certain pressure, depending upon the fuel, it is evident that this terminal pressure should be constant irrespective of the volume of the charge. Our present invention is therefore of value as it changed the explosion space with the volume of the charge so that the terminal pressures of the charges are practically constant.
Mechanisms for determining the amount of fuel in each charge are well known and any one of these devices may be employed in connection with our present invention volume thereof, a crank shaft and a driven member, a resilient connection between them comprising two relatively movable members and a spring to transmit the torque of the crank shaft from one to the other, an arm movable by one of said members according to the relative movement bet-Ween said members, and connecting mechanism between said arm and said means for varying the volume of the explosion chamber by changing kthe position of said means according to the torque of the crank shaft.
v2. In an internal combustion engine, an explosion chamber, a piston to vary the volume thereof, a crank shaft and a. driven member, a connecting device comprising parts connected to the crank shaft and to the driven member respectively, a spring to transmit force` from one of said parts to the other, one of said parts being' laterally movable according to the force transmitted, and means connecting said laterally movable part to 'said piston to cause the explosion space to vary with the force transmitted.
3. In an internal combustion engine, an explosion chamber, a piston to vary the volume thereof, a rotatable cam to move the piston, a crank shaft and a power transmitting device attached thereto comprising a driving and a .driven part and a spring between them, said driven part being rotatable relative to.` the driving part in proportion to the force transmitted, and means connected to the driven part and to the cam to rotate the cam in proportion to the force transmitted and so vary the volume of the explosion chamber.
4L. In an internal combustion engine, an explosion chamber, a piston to-vary the volume thereof, a rotatable cam to position the piston, a crank shaft and a driven shaft, a pair of hubs rotatable with said shafts and arms extending therefrom, one of said hubs being screw threaded on the other so that relative rotation between them will cause one to move longitudinally of said shafts, a spring connecting said arms and yieldable according to the force transmitted, and means actuated by the longitudinally movable hub to turn said cam to vary the explosion space with the work performed.
5. In an internal combustion engine, an explosion chamber, a working piston therein and a crank shaft connected to the piston,
resilient means to transmit the power of the engine from the crank shaft and adapted to yield according to the power transmitted, and mechanism positioned by said resilient means according to the power transmitted and independent of said piston for varying the volume of the explosion chamber ofthe engine according tov the yielding of said resilient means.
